[0025] 1. Structure

[0026] The extendable linkage lift slide 100 is composed of a base plate 110 , a scissor assembly, a drive unit 124 , a pair of first extension rails 120 and a pair of second extension rails 130 .

[0027] The base plate 110 is the foundation of the entire extendable linkage lift slide 100, and other components are mounted on the base plate 110. The scissor assembly is composed of a plurality of retractable X-shaped structures 123, each of which can be retracted to form a structure with a variable length. These X-shaped structures are connected together to form a scissor-shaped frame. The bottom and top ends of the scissor assembly are respectively provided with at least two fixed wheels 127, which are used to fix the scissor assembly to the base plate 110 and the lifting platform 128 to ensure the stability and fixity of the structure. The angle θ between the above-mentioned plurality of retractable X-shaped structures and the horizontal plane ranges from 1° to 89°.

[0028] The drive unit 124 is located on the base plate 110 and is responsible for transmitting power to the scissor assembly to achieve precise displacement of the lifting table 128. It includes a drive motor and a transmission assembly. The drive motor is an electric motor, which is usually fixed to the base plate 110. Its main function is to convert electrical energy into mechanical displacement, providing sufficient torque and speed to drive the displacement of the lifting slide. This can be controlled through the power supply connection. The transmission assembly is the connecting part between the motor and the scissor assembly, which is used to convert the rotational motion of the motor into linear displacement of the scissor assembly. The selection of the transmission assembly depends on the specific application requirements, including but not limited to the following:

[0029] 1. Belt: Driven by belt, this is a common transmission mechanism, especially suitable for occasions that require a larger range of motion and smooth movement.

[0030] 2. Screw: A rotating screw connected to a motor that converts force into vertical displacement of the scissor assembly through rotation.

[0031] 3. Gears: Gear systems can provide high-precision transmission and are particularly suitable for applications that require accurate positioning.

[0032] 4. Pneumatic cylinder or hydraulic cylinder: In some applications that require stronger power and high output force, pneumatic cylinder or hydraulic cylinder can be used as a transmission component to push the scissor lift assembly through air pressure or oil pressure.

[0033] The multiple telescopic X-shaped structures 123 are equipped with a rotating shaft 126, which is usually located at a key position of the telescopic X-shaped structure 123. The rotating shaft 126 is connected to the transmission assembly. If it is a two-stroke link lift slide, its rotating shaft 126 will be located at 1 / 2 of the scissor assembly. If it is a three-stroke link lift slide, its rotating shaft 126 will be located at 1 / 3 of the distance between the scissor assembly and the bottom plate.

[0034] A pair of first extension rails 120 are mounted on the outside of the drive unit 124 and the inside of the scissor assembly. The bottom has a first slide seat 122, and when the lifting platform 128 is driven, the first extension rails 120 will move. A pair of second extension rails 130 are mounted on the outside of the drive unit 124 and the outside of the first extension rails 120. The bottom also has a second slide seat for the first extension rails 120 to move. This multi-level rail configuration helps to ensure the stability and accuracy of the entire lifting platform during movement.

[0035] 2. Operation

[0036] The extendable travel link lift slide 100 drives the transmission assembly through a drive motor to drive the multiple retractable X-shaped structures 123 to move. Figure 2 As shown in FIG. 4 , the three-fold stroke linkage lifting slide has three retractable X-shaped structures 123 and three pairs of extension rails, namely, a pair of first extension rails 120, a pair of second extension rails 130 and a pair of third extension rails 140. The pair of third extension rails 140 is installed on the outside of the driving unit 124 and the outside of the second extension rails 130. The bottom also has a third slide seat for the first extension rail 120 to move. The transmission component applies force to the rotating shaft 126, causing the three retractable X-shaped structures 123 to begin to deform, and because the bottom and top of the three retractable X-shaped structures 123 are fixed to the base 110 by the fixed wheel 127, the middle points of the three retractable X-shaped structures 123 are pulled upward. Therefore, during the displacement process, although the driving component only causes the deformation of the retractable X-shaped structure 123 at the rotating shaft 126, the upper retractable X-shaped structure 123 also causes the upper and lower retractable X-shaped structures 123 to begin to become thinner and taller due to the mechanism relationship, and then deform and move synchronously.

[0037] During the extension of the telescopic X-shaped structure 123, the shape of the entire structure changes, which directly leads to the displacement of the lifting platform 128. This displacement can be upward or downward, depending on the direction of extension of the telescopic X-shaped structure 123, which can also be adjusted according to specific application requirements. The displacement of the lifting platform 128 also affects the movement of the extension rail. Since a pair of first extension rails 120 are connected to the lifting platform 128 through support columns, and a pair of first extension rails 120 are connected to the balance platform, the balance platform ensures that the lifting platform 128 can maintain stability and balance when rising and falling. This connection enables the bottom slide of the extension rail to follow the movement of the lifting platform 128 and perform corresponding displacement. The movement of the first extension rail 120 drives the second extension rail 130, and the movement of the second extension rail 130 affects the third extension rail 140. This cascade structure ensures the continuous movement of the rails, thereby maintaining the smooth movement of the lifting platform 128. This hierarchical extension and linkage ensures the coordination and stability of the entire system.

[0038] In general, the telescopic movement of the telescopic X-shaped structure 123 drives the displacement of the lifting platform 128, and through the linkage of the structure, the extension rail can be displaced accordingly. This structural design ensures the stability and accuracy of the utility model during operation and makes it suitable for different application scenarios.

[0039] To continue, the telescopic X-shaped structures 123 of the present invention can be stacked to achieve the required length. If a slide with double stroke is required, the number of pairs of telescopic X-shaped structures 123 must be a multiple of 2 (2 pairs, 4 pairs, 6 pairs, etc.). Similarly, as long as a slide with triple stroke is required, the number of pairs of telescopic X-shaped structures 123 must be a multiple of 3 (3 pairs, 6 pairs, 9 pairs, etc.).

[0040] by Figure 1 and Figure 3 For example, Figure 1 and Figure 3 For a slide with three times the stroke, Figure 1 The total height of the lifting platform 128 to the bottom plate is 152mm, and the displacement stroke of the intermediate drive transmission component is 51mm. When the screw moves up 51mm, the connecting rod lifting slide 100 with an extendable stroke becomes 305mm, which is 152+51*3.

[0041] See also Figure 4a and Figure 4b , Figure 4a The diagram shown is a schematic diagram of a retractable X-shaped structure 123 according to an embodiment of the present invention. Figure 4b The utility model is based on Figure 4a Schematic diagram of the extension of the retractable X-shaped structure 123.

[0042] The following example illustrates Figure 4a and 4b ,when Figure 4a When the angle θ between the retractable X-shaped structure and the horizontal plane is 30°, if the vertical height of each retractable X-shaped structure 123 is 25 cm, when the retractable X-shaped structure 123 is extended to Figure 4b When the telescopic X-shaped structure is in the state of being stretched, the angle θ between the telescopic X-shaped structure and the horizontal plane is 60°, and the vertical height of each telescopic X-shaped structure 123 will be extended to 43.3 cm according to the Pythagorean theorem. Figure 4a and 4b The indicated height of the pulley 126 would be displaced from 50 cm to 86.6 cm.

[0043] In summary, the extended-stroke linkage lift slide adopts a high-rigidity linkage structure, which effectively improves the strength of the overall structure, enabling it to withstand greater loads and adapt to a wider range of application scenarios. The slide design allows operation in the vertical or horizontal direction, and the stroke can be freely extended according to actual needs, providing multi-directional use. In addition, the retractable X-shaped structure design makes it take up less space when idle, increasing space efficiency.

In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device that includes the elements.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
